Online published on 4 June, 2019. Abstract Short wavelengths in the visible part of the electromagnetic spectrum ranging from (380–500) nm; which includes blue light, can trigger critical physiological responses including circadian rhythm synchronization and pupil constriction. Blue light cause damage to human eye, and the blue light hazard term has been coined to highlight this dangerous. The blue light can result in the demise of healthy tissue via apoptosis of photoreceptors and critical retinal pigment epithelial (RPE). This slow motion process during which damage accumulates over a lifetime has been embroiled in the different types of refractive errors i.e. (longsighted, shortsighted, and astigmatism) and pathogenesis of retinal degenerative diseases. In the present work, patients were chosen at random from different areas in Iraq and studied for the period from November 2016 to March 2017. The refractive errors of the eye were corrected using two different methods (traditional and blue light filter) spectacles. The blue-light filtering glasses were using for improving the vision of the patients and gave the best results for correction's compared with traditional glasses. This relationship was examined to investigate the potential correlation between the presence or absence of a blue filter on the refractive errors for the optics of the eye, and the inter-pupillary distance (IPD). Geo-spatial techniques were also utilized with the aid of Geographical Geographical Information System (GIS) software for analysis and interpretation of the acquired data over a wide range of Iraq. A new statistical model designed by us using Statistical Package for the Social Sciences (SPSS) to show if the results is significant or not significant. Results utilized with a statistically significant value less than 0.0001 for spherical-blue-filter, cylindrical-blue value, and axis-blue filter.
